Articles : Change of Body Fat Threshold and Exercise for the Globesity
Abstract
The present study was to verify the effect of regular exercise on percent body fat and threshold of percent body fat in women with obese. Twenty-one subjects were volunteered to participate in the present study and they were divided in three groups; the A group (n = 7). B group (n = 7), and C group (n = 7). A group participated in exercise of 40%r VO₂max, B group participated in exercise of 60% VO₂max, and C group participated exercise of 75% VO₂max for the 60days. The Subjects carried on group exercise of 20-40 minute a day. 5 times per week for 2 months in DHC. The level of statistical significance was p<.05. The results of this study were summarized as follows: The lean body mass, body water and water rate of A group following the exercise was not significantly differences among the training periods. But The lean body mass, body water, and water rate was higher than pre-exercise of groups. The percent body fat of A, C group following the exercise was significantly differences between pre and post-exercise (p<.01). The threshold of percent body fat of A, B, C group following the exercise appeared to 35, 30, and 15days. In conclusion, the result of this study confirm that long-term aerobic training and exercise intensity of 60% VO₂max played a major role in the increased lean body mass and decreased percent body fat in obese women, but it does not appear to relate body water and water rate in obese women.
Key Words: exercise, body fat threshold, globesity
